Does anyone have schematics for the Micromac IIsi -> IIci Cache/PDS adapter? I'm trying to build one (for my IIsi), and while both the PDS and Cache is documented in the developer notes, I can see that several of the pins on the cache slot which are marked at N/C in the documentation are...

HI! Does anyone know if the 64pin socket ever existed in a 45degree version? I've tried to browse Connector People page, but it's a bit difficult. So far I've only found straight ones: Single: https://www.connectorpeople.com/Connector/TYCO-AMP-TE_CONNECTIVITY/8/822019-2 Single with center post...

As some people here already know, I have spent the last couple of months getting to know the Quadra (1MB) ROMs better and get a ROM disk working for it. The basic idea was simply "if we can have a ROM disk for the SE/30, why not for my Q900?". I started by reading up on Rob Braun's excellent...

JDW has released a new video about ROM programmers and ROM programming in general, well worth watching, that includes a brief history as well: JDW’s video is also includes a few seconds on the latest CayMac vintage programmer that has been codeveloped by myself, @dougg3, @WillJac and...

An Apple retailer here in Sweden (he has sold Apple since the 1990s), listed some "new old stock", so I took a plunge and bought it all :) In the end I got: 10 XC68040RC33 3 FPU for LC/LC2 3 FPU for Color Classic 3 FPU for Classic 2 FPU for Classic 2 2 Loose 68882 FPU 1 PowerPC CPU-card I'm...

Hi! I found this device on a local auction. It connects to the scsi-port and has what looks like a VGA connector on the side. The box is marked: VideoStreamer Data Save Interface. Does anyone have any information on this device? I assume it output the screen, but do I need some drivers for it...

Don’t know if anyone else has had the same problem, but my external Zuluscsi (same case as external SCSI2D) does not fit all computers. In my case there was a collision on the IIci. Since I’m fairly handy with CAD these days and also have several printers, I decided to draw and print a new lid...

The hinge of the Apple Studio (LCD) Displays are known to break and mine where no exception :(, so I decided to recreate the broken part and 3D-print it in stainless steel. Even the threads where printed although you have to freshen them up with a tap before use. I also had to file down the...

Sometimes pictures speak for themselves 🥹☺️! jajan is helping me building another rom for it 😊😊😊

Hi! I recently bought a Macintosh Plus that came with something very interesting stuff (it also came with bag, HD, mouse, keyboard and a joystick): I'll make images and scans at a later point. Haven't tried the plus yet, but I'm curious on what to find on that drive (if it works...), looks...

Hi! I recently bought a IIci that came with some interesting cards. First it had a Carrera040 accelerator (although with a very noisy fan). But it also came with this card: Which seems to be some kind of image grabber card. I have not been able to find much information about it, but if...

HI all! I found this at a local sale: I've created a .iso for everyone to download from Macintosh Garden. Plan is also to scan all the pages. Contains a lot of useful information! Here is the link: https://macintoshgarden.org/apps/service-source-25-1999 If someone wants another format (or...

Hi! I recently acquired a Macintosh II Video Card that I want to use in my IIci with dual monitor. Do I need any special driver or extension to make this card work? I’m running S7.6.1 and have tested with two monitors (known to work and at 640x480 which this card should support). From...

Hi! I recently got a IIvi that I want to restore. Took it apart, cleaned and recapped, but it does not make any chime at all and no video output. The board looks very clean (cleaned with ISO) and the power button on the rear works ok. I tested the drives in another machine and they are fine. I...

Hi! New to the forum here, but hoping to get some advice. In my collection of old macs, I have 2 M1212 display. Both are in working order, but they make a quite annoying high pitch noise. I don’t think it’s the usual “coil wine”, because the frequency is much lower. I’ve identified it to the...
